Problem with my cassette and rear break on my new bike
Recently i have purchased a new bike and i have rode it several times and ive only just noticed this. When i spin the rear wheel quite fast i notice that my Shimano HG500 10 speed cassette 11-42T wobbles quite a bit. Also my break pads are rubbing on the rear wheel and not the front so im not sure if these problems are linked. All help will be much appreciated.
